no. 1 approach

[0032] FIG. 1 is a diagram showing an example of the configuration of an optimal control system according to the first embodiment of the present invention. As shown in Figure 1, the optimal control system 10 related to this embodiment includes: a local control device 3 connected with a local device 4 and controlling the local device 4; The device 3 is connected and comprehensively controls the plurality of local control devices 3 .

[0033] In Fig. 1, the local control device 3 includes: a local control part 31 dedicated to controlling the local device 4; Standardize control information. In addition, the control information standardization interface 1 includes a physical quantity conversion unit 11 and a control condition information storage unit 12 .

[0034]The physical quantity conversion unit 11 converts the local physical state quantity output from the local device 4 into a standard physical state quantity represented by a predetermined standard physical quantity (for e...

[0074] FIG. 2 is a diagram showing an example of the configuration of an optimal control system according to a second embodiment of the present invention. As shown in Figure 2, the optimal control system 10a related to the second embodiment includes: a local control device 3a connected with a local device 4 and controlling the local device 4; The overall control device 2a that performs comprehensive control of the plurality of local control devices 3a. In addition, in FIG. 2, the same code|symbol is attached|subjected to the component with the same function as FIG.

[0075] In the optimal control system 10a related to the second embodiment, compared with the optimal control system 10 (see FIG. 1 ) related to the first embodiment, the control information standardization interface 1 is included in the overall control device 2a but not included. This point is different from the local control device 3a.

[0076] The local control device 3a outputs the local physical state quanti...

no. 3 approach

[0082] 3 is a diagram showing a configuration example of an optimal control system according to a third embodiment of the present invention. As shown in FIG. 3, the optimal control system 10b related to the third embodiment includes a local control device 3b connected to a local device 4 and controlling the local device 4, and a local control device 3b connected to a plurality of local control devices 3b and controlling the plurality of local control devices 3b. The local control device 3b is the overall control device 2b for comprehensive control. In addition, in FIG. 3, the same code|symbol is attached|subjected to the component with the same function as FIG.

[0083] Compared with the optimal control system 10 (refer to FIG. 1 ) related to the first embodiment, the optimal control system 10b related to the third embodiment is included in the overall control device 2b but not included in the local control unit 11. This is different for device 3b.

Abstract

An optimizing control system includes at least a local control unit for controlling at least a control apparatus, an integration control apparatus for controlling a plurality of the local control units in integration fashion, and at least a control information standardization interface arranged between the local control unit and the integration control apparatus for standardizing the control information transmitted and received between the local control unit 31 and the integration control apparatus. The control information standardization interface includes a control condition information storage unit for storing the constraints, the evaluation function and the attribute information expressed by a predetermined standard physical quantity for controlling the local apparatus, and a physical quantity converter for converting the local physical status amount acquired from the local apparatus into a standard physical status amount and converting the optical setpoint calculated by the integration control apparatus into a local control goal value.

Description

technical field [0001] The present invention relates to an optimal control method, an optimal control system, an overall control device, and a local control device for collectively optimally controlling a plurality of devices for the same purpose. Background technique [0002] In recent years, in order to prevent global warming, it is urgent that the world should work on CO 2 reduction in emissions. Here, in all fields such as factories (including plants), office buildings, public facilities / buildings, automobiles, railway vehicles, and general households, various technologies are developed to reduce energy waste and improve energy utilization efficiency. For example, in automobiles and railway vehicles, regenerative braking can be used to reuse energy, and in general households, green energy such as solar power generation is also being used. [0003] However, when a plurality of energy-related control devices are installed in a factory or a large-scale facility, it is nec...
